This book introduces summary on Personality Dimensions (R) , and is a great introductory tool book for temperament theory.The four temperaments illustrated are mostly consistent to temperament theory, however, these temperaments are expressed in colors as symbol, such as green in knowledge seekers (Inquiring Green). The contents are quite simple to be read, with few complicated terms as expressed in Keirsey's "Please Understand Me".The expression is much more practical than theoretical, career recommendations are induced in this book, much more attractive than some other books on personality. You may be disappointed if theory is pursued, but it is good for introduction in temperaments.
